Manufacturing Quality Control of Calcium L-aspartate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Ca content) | Complexometric Titration with EDTA | Calcium ions form a stable complex with EDTA at pH 10; endpoint detected by color change of Eriochrome Black T indicator. |
| Assay (L-Aspartic Acid content) | Acid-Base Titration | Free carboxylic acid groups are titrated with standardized NaOH using phenolphthalein indicator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification based on mass-to-charge ratio detection after plasma ionization. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Mass loss measured after drying at 105 C for 2 hours under controlled atmosphere. |
| Residue on Ignition | Sulfated Ash Test | Inorganic residue quantified after high-temperature ignition (700-800 C) following sulfuric acid treatment. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Chloride ions react with silver nitrate to form AgCl precipitate; endpoint detected by silver ion-selective electrode. |
| Sulfate Impurity | Turbidimetric Method | Barium sulfate precipitate formed in acidic medium; concentration determined by light scattering measurement. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode and reference electrode in 1% w/v solution. |
| Specific Optical Rotation | Polarimetry | Rotation of plane-polarized light measured at 20 C using sodium D-line; confirms chiral purity of L-aspartic acid moiety. |
| Related Substances (Impurity Profile) | HPLC-UV | Separation on reversed-phase column followed by UV detection at 200 nm to quantify structurally related impurities. |
| Microbial Limits | Membrane Filtration and Plate Count | Viable aerobic microorganisms enumerated by filtration, membrane transfer to agar media, and colony counting after incubation. |
| Particle Size Distribution | Laser Diffraction | Size distribution determined by analyzing angular variation in laser light scattering from dispersed sample. |
